United States-sized telescope views structure of Milky Way’s black hole
By: William Atkins
American-German-Dutch astronomers combined radio telescopes in California, Arizona, and Hawaii to make a very long baseline interferometer (VLBI)--a "virtual" telescope. It was able to measure the structure within Sagittarius A*, what is believed to be the supermassive black hole at the center of our galaxy, the Milky Way.

GLAST renamed Fermi Gamma-ray Space Telescope
By: William Atkins
NASA announced in February 2008 that it was holding a contest to re-name its Gamma-ray Large Area Space Telescope, or GLAST. The new name—Fermi Gamma-ray Space Telescope—was announced by NASA in August 2008 to honor Italian-American physicist Enrico Fermi (1901-1954).

Largest galactic cluster discovered: explained with dark energy
By: William Atkins
European astronomers state that 2XMM J083026+524133 has been located about 7.7 billion light-years from our solar system. They contend that its existence can only be explained through dark energy.

ABC NewsRadio axes StarStuff program – why?
By: Alex Zaharov-Reutt
ABC NewsRadio, Australia’s only 24 hour continuous news service, has axed one of its longest running programs because it wants to divert funding elsewhere. The program? StarStuff, the only space, science, astronomy and cosmology show on Australian radio. What a shame!

Galaxies could be twice as bright if not for a lot of dust
By: William Atkins
According to U.K., German, and Australian astronomers, the brightness of galaxies is really twice as bright as they appear at Earth because of extra-large amounts of interstellar dust blocking the light between them and us.

NASA's supernova hunt in Milky Way ends with discovery of G1.9+0.3
By: William Atkins
Using data from the space-based NASA Chandra X-ray Observatory and the ground-based NRAO Very Large Array, astronomers just found a supernova within our Milky Way galaxy that exploded about 140 years ago. NASA scientists took fifty years to find it.

First look: Black hole ejects plasma jet
By: William Atkins
An international group of astronomers used a series of radio telescopes to look at—for the first time—a supermassive black hole ejecting a high-speed jet of plasma particles, what is called a blazar.

Australia hopeful of radio telescope Square Kilometer Array
By: William Atkins
The Square Kilometer Array (SKA) is a major proposed telescope project that will scan the skies in the light and radio range of the electromagnetic spectrum. It is designed to offer a large collecting area of about one square kilometer (and, thus, its name). Western Australia, a prime radio wave observing site, is pursuing the desired location of the SKA telescope.

Abracadabra! Whoosh! The rings of Saturn disappear
By: William Atkins
Is a magician making Saturn's rings disappear? Actually, we are experiencing a “plane ring crossing.". The rings are appearing edge-on to Earthlings so they look to almost disappear. Such an event makes for a good time to view Saturn from your backyard telescope.
